Abstract
Systems, devices, apparatuses and methods for an active projection system that may be incorporated into spectacles, contact lenses or provided as an add-on layer to existing spectacles or lenses. The active projection system operates to generate a stimulus or stimuli for viewing by a person's eye. The stimulus or stimuli creates an image that is defocused in front of the person's retina and can assist in slowing or stopping the progression of myopia or other refractive errors in the person.
Claims19
A method of correcting refractive error of an eye, comprising:
- generating a stimulus by operating a plurality of projection modules arranged around a periphery of an optic, wherein each of the plurality of projection modules operates to generate and direct light to form the stimulus;
- and
- forming an image of the stimulus anterior or posterior to a peripheral region of a retina of the eye by directing light from the plurality of projection modules to a plurality of optical elements arranged on the optic, wherein the plurality of optical elements receives the light from the plurality of projection modules and directs the received light to form the image of the stimulus, wherein each of the plurality of projection modules further comprises:
- circuitry operative to activate a source of illumination in response to a control signal from a processor;
- a stimulus forming element arranged to form the stimulus when illuminated by the source of illumination;
- and a guide element to direct light from the stimulus forming element to at least one of the plurality of optical elements.
